Hi folks
R900 running RHEL5.
This weekend we moved up to 128GB RAM. However I'm confused with the
outputs given.
The server has 32 x 4096MB DIMM's, giving a total of 131072MB, which is
128GB.
omreport shows the following:
Total of Memory Array(s)
Attributes : Total Installed Capacity
Value : 131072 MB -- 128GB. Spot on, just what I expect
Attributes : Total Installed Capacity Available to the OS
Value : 128868 MB -- 125GB. So where did the rest go ?
# free -m
total used free shared
buffers cached
Mem: 128869 128245 623 0 659
49701
-/+ buffers/cache: 77885 50984
Swap: 16383 92 16291
So where did 3GB disappear to ?
Many thanks,
Nick
